Maybe we should have a show of hands. How many people with a 286 have
a C&T NEAT chipset?

Oh, I see. NEAT is a really rare and unusual chipset and hardly anyone
has it.

These people who had trouble, they weren't the kind of people who don't
bother to consult with their vendor, are they?

The way I see it, two answers have been provided here, mine, which is
to the effect that "it's complicated and depends on a lot of stuff,
your vendor is the best source of info", and yours, which is "no, it
won't work. well, ok, after Mr. Ngai complained about my answer, I'll
change it to be sometimes it works and sometimes it doesn't.  actually,
it's complicated, but I think you shouldn't do it"

What can I say, other people did.
